GMZ800 Synopsis For The Coastal Waters From Bonita Beach To Suwannee River- 305 Pm Est Thu Nov 14 2019
Synopsis.. High pressure along the mid atlantic coast this afternoon will move east into the atlantic through tonight as developing low pressure approaches from the gulf. Some isolated strong to severe Thunderstorms will be possible over the gulf waters tonight into overnight hours. These could produce waterspouts and gusty winds so mariners should have a method to receive marine warnings... The area of low pressure will move east across the florida peninsula tonight and then deepen as it moves east northeast into the atlantic on Friday with a trailing cold front moving south through the waters. Northeast to east winds today will veer to the southeast and south tonight, then become northwest to north with speeds increasing to cautionary or low end small craft range Friday night into Saturday. High pressure will build in over the waters during Sunday and Monday with lighter winds and lower seas expected.

Discussion
Latest rap analysis indicates surface low pressure has formed
over the eastern gulf off the coast of west central florida.

Meanwhile, an amplified and progressive split flow pattern exists
at the mid upper levels over the plains. A closed mid-level low
over south tx will quickly advance east this afternoon before
merging with a second shortwave as it digs south across the
mississippi valley. The upper level energy from this system will
enhance the surface low as it tracks across fl into the atlantic,
where baroclinic interactions will quickly strengthen it further
as it moves near the carolinas.

A pocket of deeper moisture will continue to advect north due to
persistent southeast flow in response to the veering winds from
the low. Expect the rest of today to remain cloudy with a chance
of showers and isolated thunderstorms this afternoon through the
night. As we approach the late evening and overnight hours, low
level wind profiles will become relatively favorable for organized
storms. A limiting factor will be the amount of instability
across land areas (due to loss of daytime heating) which is
expected to be meager. However, a better overlap of ingredients
will exist over the gulf due to warmer water temps and it's not
out of the question we could see a period of stronger marine
storms so we would have to watch for a few of these to work their
way on shore as waterspouts are conditionally possible.

All this cyclogenesis talk brings me to the next topic of the
associated cold front the low will drag across our area Friday.

Likely deemed to be the coldest temps we've had so far this
season... The northern nature coast will be in the 60s tomorrow
while the rest of us will stay mild. However, as the front
advances south, a prolonged period of northwest flow will advect
cooler air into the entire area this weekend. Saturday's highs
will range from the 60s to mid 70s (correct, no 80s are forecast
in lee county) and lows overnight Sunday morning will reach low
40s to possibly an upper 30 across extreme north levy. After it
dries out by Saturday morning, we will remain fairly dry through
the remainder of the period as cool high pressure dominates the
area. Fall outdoor plans are a go by Saturday (of course with the
exception of some boating concerns due elevated post-frontal
winds and seas).

Aviation
(18z issuance) east winds will gradually shift more southerly
during the day as low pressure forms over the gulf. Otherwise
prevailingVFR for sites through at least 00z. Tsra is possible
this evening into overnight hours, and a vcts has been introduced
to account for this. Low CIGS will result in lower end MVFR to
possible ifr after 06z. Tempo ifr has been added for lal and pgd
towards late overnight into early morning. MVFR CIGS are likely to
continue through the remainder of the morning from post frontal
strato-cu.

Marine
High pressure along the mid atlantic coast this afternoon will
move east into the atlantic through tonight as developing low
pressure approaches from the gulf. Some isolated strong to severe
thunderstorms will be possible over the gulf waters tonight into
overnight hours. These could produce waterspouts and gusty winds
so mariners should have a method to receive marine warnings... The
area of low pressure will move east across the florida peninsula
tonight and then deepen as it moves east northeast into the
atlantic on Friday with a trailing cold front moving south through
waters. Northeast to east winds today will veer to the southeast
and south tonight, then become northwest to north with speeds
increasing to cautionary or low end small craft range Friday night
into Saturday. High pressure will build in over the waters during
Sunday and Monday with lighter winds and lower seas expected.

Fire weather
Poor afternoon dispersions expected through Friday... An
approaching area of low pressure will bring increasing rain
chances to the region today through Friday night with cooler and
drier conditions returning for the upcoming weekend. Prevailing
winds out of the northwest will occur after the passage of the
cold front. Despite the drier air moving into the region for the
weekend, humidity values are currently forecast to remain above
critical levels with no red flag conditions expected.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
